Based on input coordinates or current location the app creates cropped image from snow and winter loading area maps as published in Eurocode 1 (Czech National Annex). Both images can be saved and used as a reference for determining the code's prescription for the loading calculations.
Sources are taken from UNMZ (Czech official publisher of national standards). The full statement of national annexes and other sources can be obtained at UNMZ information center or online from csnonline.unmz.cz. All sources used in this app were approved by UNMZ.
